typedef enum {
  LANDAU_EX2_TSSOLVE,
  LANDAU_MATRIX_TOTAL,

} LandauOMPTimers;

Values

• LANDAU_EX2_TSSOLVE - total TSSolve() time of the Landau example

• LANDAU_MATRIX_TOTAL - total time spent constructing the Jacobian and mass matrices

• LANDAU_OPERATOR - time inside the Landau operator evaluation

• LANDAU_JACOBIAN_COUNT - number of Jacobian evaluations (stored as a count, reused as a timer slot)

• LANDAU_JACOBIAN - time inside Jacobian construction

• LANDAU_MASS - time inside mass-matrix construction

• LANDAU_F_DF - time evaluating the distribution function and its derivatives

• LANDAU_KERNEL - time inside the Landau collision kernel

• KSP_FACTOR - time inside the KSP factor stage when using a direct solver

• KSP_SOLVE - time inside KSPSolve()

• LANDAU_NUM_TIMERS - sentinel; equals the number of timer slots allocated in LandauCtx
